WALTER I-I. EASTLACK, OF MERCHNTVILLE, NEW JERSEY.

NON-REFILLABLE BOTTLE.

To all 'whom it may concern:

Be it known that I, WALTER I-I. EAST- LACK, a citizen of the UnitedStates, residing at Merchantville, county of Camden, State of NewJersey, have invented a new and useful Non-Refillable Bottle, of whichthe following is a specification.

My present invention consists of a novel construction of a bottle whichmay be economically manufactured and which is con structed in such amanner that the same is practically incapable of b eing refilled ortampered with.

It further consists of a novel construe tion of a valve mechanism whichis adapted to be inserted in the neck of the bottle and whichv wheninserted in position cannot be removed.

It further consists of a novel construction of a non-refillable bottlewherein the bottle neck is provided with a plurality of grooves withwhich are adapted to co-act resilient extensions of a shell, whichlatter is provided with a valve seat and a plurality of baffle plates,there being also provided a novel construction of a valve member adaptedto co-act with said seat.

lt further consists of other novel features of construction, all as willbe hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of these in strumentalities asherein shown and described.

Figure 1 represents a sectional elevation of a non-reiillable bottleembodying my in-4 vention. Fig. 2 represents a sectional elevation of mydevice wherein the valve mech-- anism is adapted to be inserted duringthe process of making the bottle. Fig. 3 represents a sectionalelevation of my novel device the same being shown in detached position.

Similar numerals of reference indicate corresponding parts in thefigures.

internal grooves therein and in the present instance I have shown two ofsuch grooves as indicated at 2 and 3.

4 designates a casing or shell provided with outwardly extendingresilient flanges 5 and 6 which are adapted to interlock with thegrooves 2 and 3 respectively.

7, 8, 9 and 10 designate baffle members, each of which preferablyconsists of a disk having a portion removed so that a little more thanhalf of the disk is left, it being understood that any desired number ofsuch disks may be employed and that they are arranged in staggered orderand in different horizontal plane so as to prevent tampering with thevalve mechanism.

11 designates an extension having a concal seat 12 with which co-acts aball valve 1S to which is secured a rod 14 which latter is also securedto a ball or weight 15 which if desired may be of a diiferent'weight orsize than the valve 13. The lower end of the shell is bifurcated ordivided upwardly from below, one section bent outwardly, forming thebottom resilient flange 5, and

the other section being bent inwardly forming the conical valve seat 11.

16 designates a cross rod secured to the rod 14 which limits themovement of the valve 13 toward the mouth of the bottle and preventssuch valve from engaging with the lower baffle 10 and furthermorepreventing the weight 15 from closing the valve seat The members 7 8, 9and 10 may the shell with its baffle plates and valve seat arepractically integral as such and they form as it were a single memberwhich may be forced into the neck of the bottle, when as stated, theresilient flanges being outturned :or salient spring into the grooves 2,3, re-

spectively and so the device in its entirety is seated immovably inposition, the shell and its flanges fittingv tightly against thecontiguous portions of the neck of the bottle and the grooves, 2, 3,therein, thus preventing the passage of an implement to the valve 13 toraise the same, it being noticed that the valve seat 12 extends belowthe lower flange 5 of the shell and serves to defiect such implementshould the latter possibly be pushed under said flange, and thus theexterior of the valve seat acts as a guard against the upward opening ofsaid valve.

In Fig. 1, my novel device is shown as being placed in position withrespect to a cold and nished bottle, in which case the shell 4, havingthe baffle plates, valve and its adjuncts in assembled position, ispushed into the bottle from the mouth in the direc tion of the arrowuntil the resilient members 5 and 6 interlock with the grooves 2 and 3respectively, after which it is impossible to remove the shell 4 and itsadjuncts without breaking the neck of the bottle.

In Fig. 2 I have illustrated one manner in which the shell 4 and its adjuncts are placed in position while the bottle is hot and during itsprocess of manufacture and before the bottom is closed. In this case theshell 4 is drawn toward the mouth of the bottle after the bottle isfilled, until the flexible portions 5 and 6 interlock with the grooves 2and 3 respectively. Owing to the manner in which the baliie plates ordisk are arranged, it is impossible for one to hold the valve in openposition by the insertion of a wire or other implement. When the bottleis inclined or tilted the valve 13 will move from its seat 12 and permitthe fluid within the bottle to pass therefrom, and owing tothe provisionof the ball or weight 15, the valve 12 will positively return toitsclosed position when the bottle is brought to a vertical position.

Special attention is directed to the fact that in my present device thebaflle plates serve a double function, inasmuch as they not only preventany tampering with the valve mechanism but they also prevent the airfrom escaping from the bottle when any one attempts to refill thebottle. It will also be apparent that owing vto the provision of theweight 15, the valve 13 will close in time to prevent air escaping orflowing thereinto, such as is the case in prior devices of thischaracter with which I am familiar. The baille plates also serve toregulate the flow of the liquid and cause a more uniform flow.

In the embodiment seen in Fig. 2, the shell 4 and its adjuncts areplaced in the bottle in the process of manufacture, but the shell 4 isnot drawn into this position seen in Fig. 2

`until the bottle is filled, after which, by

means of any suitable implement engaging vone of the baffles, such asfor example the baffle 7, the shell 4 is drawn outwardly to ward themouth of the bottle until the resilient flanges 5 and 6 interlock withthe grooves 2 and 3, respectively, it being of course understood thatany suitable packing material may be employed in conjunction with theshell 4, if desired.

When my novel device is employed it is unnecessary to employ anindependent stopper, although the same may be used, if desired. Theshell 4 may be made of any desired material and is preferablyconstructed of material which will closely engage the wall of the bottleneck in order to form an air tight engagement therewith. My novelconstruction of the valve seals the opening in such a manner that no aircan enter into or escape from the bottle.

It will now be apparent that I have devised a novel and usefulconstruction of a non-refillable bottle, which embodies the features ofadvantage enumerated as desirable in the statement of the invention andthe above description, and while I have, in the present instance, shownand described a preferred `embodiment thereof which has been found inpractice to give satisfactory and reliable results, it is to beunderstood that the same is susceptible of modification in variousparticulars Without departing from the spirit or scope of the inventionor sacrilicing any of its advantages.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is z- In a non-refillable bottle, a bottle, abafflecarrying shell fitting tightly the interior wall of the neckthereof, an outturned resilient flange on the upper part of said shelladapted to interlock withl said wall, and a bifurcation on the lower endof said shell, y

one section of said bifurcation extending outwardly comprising aresilient flange which is adapted to interlock with said wall, and thevother section thereof extending inwardly comprising a conical valveseat, and

a gravitating valve on said seat.
